Anisotropy of Spherical Sound Waves

Abstract

THE amplitude of vibrations on the wave surface of a spherical light wave may, or may not, be homogeneous. According to the classical electromagnetic theory of light, for a spherical wave emitted by a linear oscillator, the intensity is at a maximum in the direction perpendicular to the axis of the oscillator, and at a minimum in the direction of prolongation of the axis.
